Hi ST Community
Is it possible to use the ADC polling/DMA/IT in STOP2 mode. The application is to develop a low power platform for ADC sampling and go back to sleep. After a certain period send this data over BLE.

Hi @STTwo-32
Thanks for sharing the table. I have couple more questions
1. Any necessary steps to be taken to put ADC block in low power mode
2. After waking up from STOP2 mode, any re-initialization of ADC to be done so that ADC can be used in RUN mode?

You can follow the same steps as on this example.
